Abstract

A device for destroying snow-ice formations on roads and sidewalks, hung on an energy tool containing a natural drum, in which spring rings with two ends bent outward, which are a working tool, are strung on the rods (ties), characterized in that the working tool has a ring-shaped shape a disk mounted on the drum with the possibility of radial movement, the outer working part of which is made pointed in the form of a continuous or intermittent blade.

Description

DEVICE FOR DESTRUCTION OF SNOW-ICE FORMATIONS ON ROADS AND SIDEWAYS.

The utility model relates to the public utilities sector, in particular, to machines for breaking snow and ice formations on roads and sidewalks.

Known Working body of the ice-cutting machine according to the description of the invention to and.with. USSR R 1168647, class E 01 H 5/12, published in BI NS 27 07/23/85. (1).

This working body contains a horizontally located drive shaft and drummers installed along it, connected with the shaft by means of flexible rods, which are made rigid in a plane perpendicular to the axis of rotation of the shaft, and the impactors are made in the form of a truncated cone and are mounted on flexible rods with a smaller base with the possibility of rotation about its axis.

The disadvantage of this working body is that the design of flexible connections (rods) made in the form of plates pairwise connected by fingers (axes) is unsuccessful. These connections are not reliable, in addition, the drummers after interaction (collision) with ice (the treated surface) become unbalanced, the stability of rotation of the drum shaft is violated. This device is unsafe when used in crowded city conditions, and on the roads in general.

Also known is a device and tool for cleaning metal surfaces, as well as roads, published in a peer-reviewed journal on the subject of Utility, household and commercial equipment for 1996, fP 4, s 4, serial number 4.33.26 (2).

This device is a working body in the form of a drum elongated up to one meter in diameter from 300 to 500 mm, in which spring rings with two ends bent to the load, which are a working tool, are strung on 4 or 6 rods (ties). The drum is driven from the electric motor through a belt drive, and the entire device begins to move in front of the electric car or behind the tractor. The numerous ends of the spring rings with the help of centrifugal force destroy the ice on the sidewalks, leaving no defects on the asphalt.

The disadvantage of this device is that the bent outward ends of the spring rings inefficiently (with low efficiency) destroy the ice layer on the road, since they do not have pronounced sharp cutting edges and blades.

The purpose of the development and creation of the proposed device for the destruction of snow-ice formations on roads and sidewalks is to improve the quality of its work, efficiency and reliability through the use of cutting tools having a working part with sharp cutting blades.

This goal is achieved by the fact that the device mounted on an energy tool, for example, on a wheeled tractor, contains a drive drum, and a lot of U-shaped eyes are mounted on the drum along a helix, on which drummers (hammers) in the form of ring-shaped disks are mounted on the axes, having the possibility of free radial movement by a certain amount relative to the axes on which they are mounted. This allows you to copy the roughness of the road (sidewalk).

When the drum rotates and the tractor moves along a snow-ice formation on the road, a lot of shockers destroy the snow-ice formation.

A similar device with manual control can be created for cleaning small areas and narrow sidewalks, which will be based on the frame, and the drum with percussions is driven by an electric motor or internal combustion engine. From the same engine through the transmission mechanism will move on two wheels and the entire unit, and the control unit is manual,

As a close analogue of the proposed device, you can take the Device and tool for cleaning metal surfaces, as well as roads (E),

The list of figures in the drawings.

Figure 1 shows the proposed device, a side view in section along aa.

Figure 2 shows the same device, a top view. Fig. 3 shows an annular-shaped drummer pointed at the outer working part in the form of a solid blade. Figure 4 shows the hammer, the outer part of which is made in the form of an intermittent blade.

The proposed device contains the following units, assemblies and parts. Frame 1 is the basis of the entire device (FIGS. 1 and 2). Two brackets E are attached to the front surface of the transverse front beam of the frame 1, intended for fastening the device to the tractor linkage mechanism. Two support wheels 3 are also attached to the front of the frame 1, equipped with a screw mechanism for raising or lowering the device and adjusting the gap between the drummers and the road surface.

The gearbox 4 is also mounted on the frame 1, which receives rotation from the tractor power take-off shaft and transfers to the two sides of the frame, respectively, through the couplings 5 and the thrust bearings 6 to two V-belt drives 7; driven pulleys of V-belt drives 7 are mounted on two ends of the shaft 8, fixedly attached to the drum 9.

(A/

- 3 Shaft 8 is mounted on two bearings mounted respectively on two longitudinal beams of the frame (Fig. E),

A plurality of P-shaped lugs 10 are attached on the drum 9 in a helical fashion, and drummers 11 having the shape of an annular disk are mounted on the axes, while the drummers 11 have the possibility of free radial movement by a certain amount relative to the axes on which they are mounted (Fig. 1).

The outer working part of the striker 11 is made pointed in the form of a solid (Fig. 3) or intermittent (Fig. 4) blade. Depending on the strength of a snow-ice or ice formation on the road, when the device is used, strikers with a solid or intermittent blade are used.

A safety casing 12 is fixedly attached to the frame 1, which simultaneously covers the sides of the device. An elastic rubber shield 13 is attached to the rear housing 12 in the direction of travel of the device. Using the attachment unit 2 and 14, the device is mounted, for example, on a tractor.

The proposed device operates as follows. The tractor driver sets the drum 9 on a level ground using the screw mechanisms of the support wheels 3 so that the gap between the drummers 11, which are in the lowest position from the surface of the platform, is optimal, in which the layer of snow and ice formation on the road will be destroyed.

Then the tractor driver enters an ice-covered section of the road or sidewalk, lowers the drum 9 to the lower working position, turns on the tractor power take-off shaft, turns on the tractor’s working gear

and begins to move. When rotating the drum 9

- 4 drums (along the width of the road surface) destroy the snow-ice formation on the road,

And the destroyed and crushed ice on the surface of the road can be removed with a sweeping brush (road).

A prototype of the proposed device for the destruction of snow-ice formations on roads and sidewalks was made and tested with a positive result at the Omsk Siberian Plant. Fighters of the revolution in January EOOO year.
